HYDROCARBON SAD-IRON.

Specification of Letters Patent.

Patented Oct. 19, 1909.

Application filed March 18, 1907. Serial No. 362,887.

- for use either with alcohol, gasolene, or any I iron, etc., and will also permit them to be other hydro-carbon oil adapted for similar purposes, and in which the parts are separable at points which will permit their removal for an initial heating, for cleaning the reassembled without difliculty byinexperienced persons.

My invention also has for an object the construction of such a sad iron with a minimum amount of machine work and of inexs' pensive parts.

A still further object is the utilization of the incoming air currents to'carry ofi' the heat which would otherwise radiate to the vicinity of the handle.

In the following description reference is had to the accompanying drawings in which,-

Figure 1 is a general side View of a sad iron embodying my invention. Fig. 2 is a general top view of the same. Fig. 3 is a detail top view of the mixer. Fig. 4 is a cross sectional view of the same. Fig. 5 is a side view of the nozzle. Fig. 6 is a detail front view of the nozzle fork. Fig. 7 is an enlarged sectional View of the nozzle tip. Fig. Sis a detail top view of the base. Fig. 9 is a longitudinal sectional view of the sad iron.

Like parts are-identified by the same ref-' erence characters throughout the several views. r

A hollow base 1 preferably of triangular form is provided with interior heat absorbing ribs 2, and a notch3 at one side for the admission of air. A cap plate/i is adapted to rest upon and cover the base. It is provided with a hook 5 whichengages in an aperture 6 in the front wallof the base at the apex, and nearone rear corner, a cam 8,

rotatably mounted on the cap plate, is adapted to engage a headed post 9 connected with the base and preferably comprising a screw, threaded into a socket in the base and adjustable therein. The cam 8 is provided with a notch 11, adapted to permit the screw head to pass through it when the cap plate is removed or replaced and the upper face of the cam is wedge-shaped in cross section so that when the cap plate is in position the cam may'be rotated to move it with a wedging action under the screw head and thus co- 0 crate with the hook 5 in holding the cap p ate in position.

A storage tank 15 is provided with an inclined tubular arm 16 connecting with a nozzle tube 17, which nozzle tube is adapted to rest in anotch formed in the rear wall of the base with the front end of the nozzle tube projecting within the baseand provided with a nozzle tip. The nozzle tube 17 is provided with fork arms 20 near the nozzle tip, which fork arms are ada- )ted to straddle the burner tube as hereinafter explained.

I The nozzle tip comprises a tubular cap piece having a central delivery aperture 21, the side walls ofthe tubular portion being screw threaded at 22 and adapted for threaded engagement with the interior surface of the tube 17. A fillin of asbestos, wool or similar material 24 1s inserted in the tubular cavity of the nozzle tip and held in position by a pair of gauze screens 25.

A shallow forwardly tapering dish 31 is provided with flanges 32 on its side margins which rest in notches 33 in the wall of the base near its front end portion directly underneath the cap plate. This dish is provided with a rear wall 3d having an aperture 35 adaptedto receive the nozzle tip, as indicated in dotted lines in Fig. 3, and im- .mediately in front of this tip an open ended along the central portion of the sad iron base. This 'burner't-ube. is provided with a series of slits38' on its under side adapted to permit the escape of gas in the ordinary manner.

It will be understood that-a jet of hydro carbon vapor discharged through the nozzle aperture 21 will be delivered into the miving tube 57 and mixed with air entering said tubef from the dish bl during its passage tof the burner tube. The dish covers only the tor-wind portion of the burner tube leaving the nozzle tube 17 exposed to the heat of the burner tlame, whereby hydrocarbon oil-from the tank or reservoir to will be vaporized before reaching the. nozzle aperture Til.

4D is anordimtry valve stem provided with a needle valve controlling the delivery of the combustible iluid.

Referring to Fig. :3 it; will be observed that the cap plate is provided with apertures .42 adaptedito admit air to the dish 31. The

passage of this air through the cap plate and dish keeps the plate and the forward end of the handle continuously cool, the under surface ol the rear portion of the 'ap plate being provided with a protecting shield 43 composed of non-heat comlu tin material, whereby the rear portion of the plate is prevented from receiving an objectionable amount of heat from the burner.

H is an ordinary handle rigidly secured to the cap plate by screws l5.

l6 is an ordinary screw eye provided with a nozzle cleaning tool J of line wire adapted to enter the nozzle aperture 21. By means of the screw eye this wire is normally attached to the handle of the sad iron so that it Will always be present and ready for use in case the nozzle aperture should become clogged.

It will be observed that by releasing the cam 8 from the headed post; 9 and removing the -cap plate, it is then possible to remove the tank and burner tube and to separately remove the dish 31, mixer tube and burner.

these parts being freely movable as soon as the cap plate is released. This feature ol great importance in facilitating keeping the parts clean and in'good condition. l lspecial'ly the feature of having the nozzle tube and mixer tube readily separable and of having both these parts removable from the base Without the necessity of releasing any attachments except those connected with the cap plate. This feature of having ,the parts readily separable also facilitates heating the burner, nozzle tube and the reservoir prepara tory to lighting the burner, since by removi n the several parts a pad saturated with hydrocarbon oil may be placed in the base and the nozzle tube and reservoir will be loosely over it and covered by the cap plate so that by igniting the pad sufiicient, heat will be absorbed by the reservoir and nozzle tube to vaporize or partially vaporize the liquid v after which the pad can be removed and the parts assembled While hot and the burner ign ted, While the fluid is still vaporized in the no/zzle.

a l l Having thus described my invention what 1 claim as new and desire to secure by Letters Patent is,

1. In a sad iron ol the described class the combination ol a hollow base, a. removable cap plate therefor. a reservoir pro\ ided with. a nozzle tube and nozzle tn'ojectini: loosely through one wall of the base. a dished plate interposed between the forward potl ui ot the cap plate and the base-and loosely engaging the nozzle, a mixing tube on the dished plate having an open end adapted to receive vapor discharged trout said nozzlc,- said tlllXllllf tube being doubled tuicltwardly below the plate.-and a burner tube in cominunication with the lower end ot the mixing tube; said dished plate and nozzle tube being held in position by the cap.
